In an IDE like Spyder, import the module and then run the module individually. enter image description here

In the Divi Theme Documentation, it says that the theme comes with access to 'ePanel' which also has an 'Integration' section.

You should be able to add this code:

<script>
 $( ".et-pb-icon" ).click(function() {
 $( this ).toggleClass( "active" );
 });
</script>

into the the box that says 'Add code to the head of your blog' under the 'Integration' tab, which should get the jQuery working.

Then, you should be able to style your class to what ever you need.

It looks like the events are not bubbling. Try this:

$("#mybutton").click(function(){
  var oldval=$("#mytext").val();
  $("#mytext").val('Changed by button');
  var newval=$("#mytext").val();
  if (newval != oldval) {
    $("#mytext").trigger('change');
  }
});

I hope this helps.

I tried just a plain old $("#mytext").trigger('change') without saving the old value, and the .change fires even if the value didn't change. That is why I saved the previous value and called $("#mytext").trigger('change') only if it changes.

If you want to fire the event only on changes of your input use:

$('.s').bind('input', function(){
  console.log("search!");
  doSearch();
});

Take a look at Google Play Location Samples

Location Updates using a Foreground Service: Get updates about a device's location using a bound and started foreground service.

Location Updates using a PendingIntent: Get updates about a device's location using a PendingIntent. Sample shows implementation using an IntentService as well as a BroadcastReceiver.

This worked for me, seems to work as global :

Dim savePos(2 To 8) As Integer

And can call it from every sub, for example getting first element :

MsgBox (savePos(2))

The safest way to have a PDF display instead of download seems to be embedding it using an object or iframe element. There are also 3rd party solutions like Google's PDF viewer.

See Best Way to Embed PDF in HTML for an overview.

There's also DoPDF, a Java based In-browser PDF viewer. I can't speak to its quality but it looks interesting.

For portability, try this:

#ifdef _WIN32
#include <conio.h>
#else
#include <stdio.h>
#define clrscr() printf("\e[1;1H\e[2J")
#endif

Then simply call clrscr(). On Windows, it will use conio.h's clrscr(), and on Linux, it will use ANSI escape codes.

If you really want to do it "properly", you can eliminate the middlemen (conio, printf, etc.) and do it with just the low-level system tools (prepare for a massive code-dump):

#ifdef _WIN32
#define WIN32_LEAN_AND_MEAN
#include <windows.h>

void ClearScreen()
{
  HANDLE                     hStdOut;
  CONSOLE_SCREEN_BUFFER_INFO csbi;
  DWORD                      count;
  DWORD                      cellCount;
  COORD                      homeCoords = { 0, 0 };

  hStdOut = GetStdHandle( STD_OUTPUT_HANDLE );
  if (hStdOut == INVALID_HANDLE_VALUE) return;

  /* Get the number of cells in the current buffer */
  if (!GetConsoleScreenBufferInfo( hStdOut, &csbi )) return;
  cellCount = csbi.dwSize.X *csbi.dwSize.Y;

  /* Fill the entire buffer with spaces */
  if (!FillConsoleOutputCharacter(
    hStdOut,
    (TCHAR) ' ',

  if (!FillConsoleOutputAttribute(
    hStdOut,
    csbi.wAttributes,
    cellCount,
    homeCoords,
    &count
    )) return;

  /* Move the cursor home */
  SetConsoleCursorPosition( hStdOut, homeCoords );
}

#else // !_WIN32
#include <unistd.h>
#include <term.h>

void ClearScreen()
{
  if (!cur_term)
  {
     int result;
     setupterm( NULL, STDOUT_FILENO, &result );
     if (result <= 0) return;
  }

   putp( tigetstr( "clear" ) );
}
#endif

Custom Tooltips with pure CSS - no JavaScript needed:

Example here (with code) / Full screen example

As an alternative to the default title attribute tooltips, you can make your own custom CSS tooltips using :before/:after pseudo elements and HTML5 data-* attributes.

Using the provided CSS, you can add a tooltip to an element using the data-tooltip attribute.

You can also control the position of the custom tooltip using the data-tooltip-position attribute (accepted values: top/right/bottom/left).

For instance, the following will add a tooltop positioned at the bottom of the span element.

<span data-tooltip="Custom tooltip text." data-tooltip-position="bottom">Custom bottom tooltip.</span>

How does this work?

You can display the custom tooltips with pseudo elements by retrieving the custom attribute values using the attr() function.

[data-tooltip]:before {
    content: attr(data-tooltip);
}

In terms of positioning the tooltip, just use the attribute selector and change the placement based on the attribute's value.

Example here (with code) / Full screen example

Full CSS used in the example - customize this to your needs.

    display: inline-block;

As others have noted, golang does not have a ternary operator or any equivalent. This is a deliberate decision thought to intend readability.

This recently lead me to a scenario constructing a bit-mask in a very efficient manner became hard to read when written idiomatically because it took up a lot of lines of screen, very inefficient when encapsulated as a function, or both, as the code produces branches:

package lib

func maskIfTrue(mask uint64, predicate bool) uint64 {
  if predicate {
    return mask
  }
  return 0
}

producing:

        text    "".maskIfTrue(SB), NOSPLIT|ABIInternal, $0-24
        funcdata        $0, gclocals·33cdeccccebe80329f1fdbee7f5874cb(SB)
        funcdata        $1, gclocals·33cdeccccebe80329f1fdbee7f5874cb(SB)
        movblzx "".predicate+16(SP), AX
        testb   AL, AL
        jeq     maskIfTrue_pc20
        movq    "".mask+8(SP), AX
        movq    AX, "".~r2+24(SP)
        ret
maskIfTrue_pc20:
        movq    $0, "".~r2+24(SP)
        ret

What I learned from this was to leverage a little more Go; using a named result in the function (result int) saves me a line declaring it in the function (and you can do the same with captures), but the compiler also recognizes this idiom (only assign a value IF) and replaces it - if possible - with a conditional instruction.

func zeroOrOne(predicate bool) (result int) {
  if predicate {
    result = 1
  }
  return
}

producing a branch-free result:

    movblzx "".predicate+8(SP), AX
    movq    AX, "".result+16(SP)
    ret

which go then freely inlines.

package lib

func zeroOrOne(predicate bool) (result int) {
  if predicate {
    result = 1
  }
  return
}

type Vendor1 struct {
    Property1 int
    Property2 float32
    Property3 bool
}

// Vendor2 bit positions.
const (
    Property1Bit = 2
    Property2Bit = 3
    Property3Bit = 5
)

func Convert1To2(v1 Vendor1) (result int) {
    result |= zeroOrOne(v1.Property1 == 1) << Property1Bit
    result |= zeroOrOne(v1.Property2 < 0.0) << Property2Bit
    result |= zeroOrOne(v1.Property3) << Property3Bit
    return
}

produces https://go.godbolt.org/z/eKbK17

    movq    "".v1+8(SP), AX
    cmpq    AX, $1
    seteq   AL

Just add attribute runAllManagedModulesForAllRequests="true" to system.webServer\modules in web.config.

This attribute is enabled by default in MVC and Dynamic Data projects.

When you have many HTML inputs named C[] what you get in the POST array on the other end is an array of these values in $_POST['C']. So when you echo that, you are trying to print an array, so all it does is print Array and a notice.

To print properly an array, you either loop through it and echo each element, or you can use print_r.

Alternatively, if you don't know if it's an array or a string or whatever, you can use var_dump($var) which will tell you what type it is and what it's content is. Use that for debugging purposes only.

You can use the row_number() function for this.

INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
    SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
            row_number() over (order by (select NULL))
    FROM PM_Ingrediants 
    WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
                             )

If you want to start with the maximum already in the table then do:

INSERT INTO PM_Ingrediants_Arrangements_Temp(AdminID, ArrangementID, IngrediantID, Sequence)
    SELECT @AdminID, @ArrangementID, PM_Ingrediants.ID,
           coalesce(const.maxs, 0) + row_number() over (order by (select NULL))
    FROM PM_Ingrediants cross join
         (select max(sequence) as maxs from PM_Ingrediants_Arrangement_Temp) const
    WHERE PM_Ingrediants.ID IN (SELECT ID FROM GetIDsTableFromIDsList(@IngrediantsIDs)
                             )

Finally, you can just make the sequence column an auto-incrementing identity column. This saves the need to increment it each time:

create table PM_Ingrediants_Arrangement_Temp ( . . .
    sequence int identity(1, 1) -- and might consider making this a primary key too
    . . .
)

To improve on the other answer's SQL query (which is great!), here is a revised query. It also includes constraint names, inheritance information, and a data types broken into it's constituent parts (type, length, precision, scale). It also filters out columns that have been dropped (which still exist in the database).

SELECT
    n.nspname as schema,
    c.relname as table,
    f.attname as column,  
    f.attnum as column_id,  
    f.attnotnull as not_null,
    f.attislocal not_inherited,
    f.attinhcount inheritance_count,
    pg_catalog.format_type(f.atttypid,f.atttypmod) AS data_type_full,
    t.typname AS data_type_name,
    CASE  
        WHEN f.atttypmod >= 0 AND t.typname <> 'numeric'THEN (f.atttypmod - 4) --first 4 bytes are for storing actual length of data
    END AS data_type_length, 
    CASE  
        WHEN t.typname = 'numeric' THEN (((f.atttypmod - 4) >> 16) & 65535)
    END AS numeric_precision,   
    CASE  
        WHEN t.typname = 'numeric' THEN ((f.atttypmod - 4)& 65535 )
    END AS numeric_scale,       
    CASE  
        WHEN p.contype = 'p' THEN 't'  
        ELSE 'f'  
    END AS is_primary_key,  
    CASE
        WHEN p.contype = 'p' THEN p.conname
    END AS primary_key_name,

I was getting the below error in my 32 bit application.

Error: Retrieving the COM class factory for component with CLSID {4911BB26-11EE-4182-B66C-64DF2FA6502D} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

And on setting the "Enable32bitApplications" to true in defaultapplicationpool in IIS worked for me.

Just remove the : in your Quantity. Make sure that your attribute is the same with the parameter you include in the code, like this:

Private Sub DataGridView1_CellFormatting(ByVal sender As Object, ByVal e As DataGridViewCellFormattingEventArgs) Handles DataGridView1.CellFormatting
    For i As Integer = 0 To Me.DataGridView1.Rows.Count - 1
        If Me.DataGridView1.Rows(i).Cells("Quantity").Value < 5 Then
            Me.DataGridView1.Rows(i).Cells("Quantity").Style.ForeColor = Color.Red
        End If
    Next
End Sub

You have to catch the SIGINT signal (we are talking POSIX right?)

See @Gab Royer´s answer for sigaction.

Example:

#include <signal.h>
#include <stdlib.h>
#include <stdio.h>

void my_handler(sig_t s){
           printf("Caught signal %d\n",s);
           exit(1); 

}

int main(int argc,char** argv)
{
   signal (SIGINT,my_handler);

   while(1);
   return 0;

}

I will like to answer this with numpy, great powerful array computation module in python.

Here is code snippet:

import numpy
a = ['Jellicle', 'Cats', 'are', 'black', 'and', 'white,', 'Jellicle', 'Cats', 
 'are', 'rather', 'small;', 'Jellicle', 'Cats', 'are', 'merry', 'and', 
 'bright,', 'And', 'pleasant', 'to', 'hear', 'when', 'they', 'caterwaul.', 
 'Jellicle', 'Cats', 'have', 'cheerful', 'faces,', 'Jellicle', 'Cats', 
 'have', 'bright', 'black', 'eyes;', 'They', 'like', 'to', 'practise', 
 'their', 'airs', 'and', 'graces', 'And', 'wait', 'for', 'the', 'Jellicle', 
 'Moon', 'to', 'rise.', '']
dict(zip(*numpy.unique(a, return_counts=True)))

Output

{'': 1, 'And': 2, 'Cats': 5, 'Jellicle': 6, 'Moon': 1, 'They': 1, 'airs': 1, 'and': 3, 'are': 3, 'black': 2, 'bright': 1, 'bright,': 1, 'caterwaul.': 1, 'cheerful': 1, 'eyes;': 1, 'faces,': 1, 'for': 1, 'graces': 1, 'have': 2, 'hear': 1, 'like': 1, 'merry': 1, 'pleasant': 1, 'practise': 1, 'rather': 1, 'rise.': 1, 'small;': 1, 'the': 1, 'their': 1, 'they': 1, 'to': 3, 'wait': 1, 'when': 1, 'white,': 1}

Output is in dictionary object in format of (key, value) pairs, where value is count of particular word

This answer is inspire by another answer on stackoverflow, you can view it here

Simply replace

print $image;

with

 echo '<img src=".$image." >';

You have mentioned "user" twice in your FROM clause. You must provide a table alias to at least one mention so each mention of user. can be pinned to one or the other instance:

FROM article INNER JOIN section
ON article.section_id = section.id
INNER JOIN category ON article.category_id = category.id
INNER JOIN user **AS user1** ON article.author\_id = **user1**.id
LEFT JOIN user **AS user2** ON article.modified\_by = **user2**.id
WHERE article.id = '1'

(You may need something different - I guessed which user is which, but the SQL engine won't guess.)

Also, maybe you only needed one "user". Who knows?

Pure functional table without new lines (Just for fun)

const pureFunctionalTable = data => 
    [document.createElement('table')].filter(table => !table.appendChild(
        data.reduce((tbody, row) =>
            !tbody.appendChild(row.reduce((tr, cell) =>
                !tr.appendChild(document.createElement('td'))
                   .appendChild(document.createTextNode(cell)) || tr
                , document.createElement('tr'))
            ) || tbody, document.createElement('tbody'))) || table)[0];

Usage

document.body.appendChild(pureFunctionalTable([
    ['row 1, cell 1', 'row 1, cell 2'],
    ['row 2, cell 1', 'row 2, cell 2']
]));

Java final variable inside an inner class^[About]

inner class can use only

1. reference from outer class
2. final local variables from out of scope which are a reference type (e.g. Object...)
3. value(primitive) (e.g. int...) type can be wrapped by a final reference type. IntelliJ IDEA can help you covert it to one element array

When a non static nested (inner class) is generated by compiler - a new class - <OuterClass>$<InnerClass>.class is created and bound parameters are passed into constructor^{[Local variable on stack]}. It is similar to closure

final variable is a variable which can not be reassign. final reference variable still can be changed by modifying a state

If it was be possible it would be weird because as a programmer you could make like this

//Not possible 
private void foo() {

    MyClass myClass = new MyClass(); //Case 1. address 1
    int a = 5; //Case 2. a = 5

    Button button = new Button();

    //just as an example
    button.addClickHandler(new ClickHandler() {
        
        @Override
        public void onClick(ClickEvent event) {

            /*
            myClass.something(); //<- what is the address ?
            int b = a; //<- 5 or 10 ?

            //illusion that next changes are visible for Outer class
            myClass = new MyClass();
            a = 15;
            */
        }
    });

    myClass = new MyClass(); //Case 1. address 2
    int a = 10; //Case 2. a = 10
}

You can use:

var option_user_selection = element.options[ element.selectedIndex ].text

I'm using a dictionary to store each character of string one by one. Then iterate through second string and find the character in the dictionary, if it's present decrease the count of the corresponding key from dictionary.

class Anagram:

    dict = {}

    def __init__(self):
        Anagram.dict = {}

    def is_anagram(self,s1, s2):
        print '***** starting *****'

        print '***** convert input strings to lowercase'
        s1 = s1.lower()
        s2 = s2.lower()

        for i in s1:
           if i not in Anagram.dict:
              Anagram.dict[i] = 1
           else:
              Anagram.dict[i] += 1

        print Anagram.dict

        for i in s2:
           if i not in Anagram.dict:
              return false
           else:
              Anagram.dict[i] -= 1

        print Anagram.dict

       for i in Anagram.dict.keys():
          if Anagram.dict.get(i) == 0:
              del Anagram.dict[i]

       if len(Anagram.dict) == 0:
         print Anagram.dict
         return True
       else:
         return False

WorksheetFunction Transpose()

Instead of copying, pasting via PasteSpecial, and using the Transpose option you can simply type a formula

    =TRANSPOSE(Sheet1!A1:A5)

or if you prefer VBA:

    Dim v
    v = WorksheetFunction.Transpose(Sheet1.Range("A1:A5"))
    Sheet2.Range("A1").Resize(1, UBound(v)) = v

Note: alternatively you could use late-bound Application.Transpose instead.

MS help reference states that having a current version of Microsoft 365, one can simply input the formula in the top-left-cell of the target range, otherwise the formula must be entered as a legacy array formula via Ctrl+Shift+Enter to confirm it.

We can get a list of files inside a folder on the file system using various golang standard library functions.

1. filepath.Walk
2. ioutil.ReadDir
3. os.File.Readdir

package main

import (
    "fmt"
    "io/ioutil"
    "log"
    "os"
    "path/filepath"
)

func main() {
    var (
        root  string
        files []string
        err   error
    )

    root := "/home/manigandan/golang/samples"
    // filepath.Walk
    files, err = FilePathWalkDir(root)
    if err != nil {
        panic(err)
    }
    // ioutil.ReadDir
    files, err = IOReadDir(root)
    if err != nil {
        panic(err)
    }
    //os.File.Readdir
    files, err = OSReadDir(root)
    if err != nil {
        panic(err)
    }

    for _, file := range files {
        fmt.Println(file)
    }
}

1. Using filepath.Walk

The path/filepath package provides a handy way to scan all the files in a directory, it will automatically scan each sub-directories in the directory.

func FilePathWalkDir(root string) ([]string, error) {
    var files []string
    err := filepath.Walk(root, func(path string, info os.FileInfo, err error) error {
        if !info.IsDir() {
            files = append(files, path)
        }
        return nil
    })
    return files, err
}

2. Using ioutil.ReadDir

ioutil.ReadDir reads the directory named by dirname and returns a list of directory entries sorted by filename.

func IOReadDir(root string) ([]string, error) {
    var files []string
    fileInfo, err := ioutil.ReadDir(root)
    if err != nil {
        return files, err
    }

    for _, file := range fileInfo {
        files = append(files, file.Name())
    }
    return files, nil
}

3. Using os.File.Readdir

Readdir reads the contents of the directory associated with file and returns a slice of up to n FileInfo values, as would be returned by Lstat, in directory order. Subsequent calls on the same file will yield further FileInfos.

func OSReadDir(root string) ([]string, error) {
    var files []string
    f, err := os.Open(root)
    if err != nil {
        return files, err
    }
    fileInfo, err := f.Readdir(-1)
    f.Close()
    if err != nil {
        return files, err
    }

    for _, file := range fileInfo {
        files = append(files, file.Name())
    }
    return files, nil
}

How are these mipmap images different from the other familiar drawable images?

Here is my two cents in trying to explain the difference. There are two cases you deal with when working with images in Android:

1. You want to load an image for your device density and you are going to use it "as is", without changing its actual size. In this case you should work with drawables and Android will give you the best fitting image.

2. You want to load an image for your device density, but this image is going to be scaled up or down. For instance this is needed when you want to show a bigger launcher icon, or you have an animation, which increases image's size. In such cases, to ensure best image quality, you should put your image into mipmap folder. What Android will do is, it will try to pick up the image from a higher density bucket instead of scaling it up. This will increase sharpness (quality) of the image.

Thus, the rule of thumb to decide where to put your image into would be:

• Launcher icons always go into mipmap folder.
• Images, which are often scaled up (or extremely scaled down) and whose quality is critical for the app, go into mipmap folder as well.
• All other images are usual drawables.

it could be multiple reason, in my case under Application pool->advance setting->Enable 32 bit application (should be true).It was set to false before.

If adapter is set to AutoCompleteTextView then notifyDataSetChanged() doesn't work.

Need this to update adapter:

myAutoCompleteAdapter = new ArrayAdapter<String>(MainActivity.this, 
        android.R.layout.simple_dropdown_item_1line, myList);

myAutoComplete.setAdapter(myAutoCompleteAdapter);

Is very easy, I use this code:

Controller:

$langs = Language::all()->toArray();
return view('NAATIMockTest.Admin.Language.index', compact('langs'));

View:

<script type="text/javascript">
    var langs = <?php echo json_decode($langs); ?>;
    console.log(langs);
</script>

hope it has been helpful, regards!

In .Net 4.0, you can also call String.IsNullOrWhitespace.

final Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
      @Override
      public void run() {
        //Do something after 100ms
        Toast.makeText(c, "check", Toast.LENGTH_SHORT).show();  
        handler.postDelayed(this, 2000);
      }
    }, 1500);

In this example the loop is run every second for ten seconds:

import datetime, time
then = datetime.datetime.now() + datetime.timedelta(seconds=10)
while then > datetime.datetime.now():
    print 'sleeping'
    time.sleep(1)

Near the top of the code with the Public Workshop(), I am assumeing this bit,

suitButton = new JCheckBox("Suit");
suitButton.setMnemonic(KeyEvent.VK_Y);


suitButton = new JCheckBox("Denim Jeans");
suitButton.setMnemonic(KeyEvent.VK_U);

should maybe be,

suitButton = new JCheckBox("Suit");
suitButton.setMnemonic(KeyEvent.VK_Y);


denimjeansButton = new JCheckBox("Denim Jeans");
denimjeansButton.setMnemonic(KeyEvent.VK_U);

Use the filename property like this:

uriContent = "data:application/octet-stream;filename=filename.txt," + 
              encodeURIComponent(codeMirror.getValue());
newWindow=window.open(uriContent, 'filename.txt');

EDIT:

Apparently, there is no reliable way to do this. See: Is there any way to specify a suggested filename when using data: URI?

It would actually be more effort, but you could just build in VS.Net, run it from the regular command line (cmd.exe), and then attach to the process after it starts running. This is probably not the solution you are looking for however.

This works for me:

  recyclerView.setOnTouchListener(new View.OnTouchListener() {
      @Override
      public boolean onTouch(View v, MotionEvent event) {
          return true;
      }
  });

I have just discovered and used FETCH_HEAD. I wanted a local copy of some software from a server and I did

git fetch gitserver release_1

gitserver is the name of my machine that stores git repositories. release_1 is a tag for a version of the software. To my surprise, release_1 was then nowhere to be found on my local machine. I had to type

 git tag release_1 FETCH_HEAD 

to complete the copy of the tagged chain of commits (release_1) from the remote repository to the local one. Fetch had found the remote tag, copied the commit to my local machine, had not created a local tag, but had set FETCH_HEAD to the value of the commit, so that I could find and use it. I then used FETCH_HEAD to create a local tag which matched the tag on the remote. That is a practical illustration of what FETCH_HEAD is and how it can be used, and might be useful to someone else wondering why git fetch doesn't do what you would naively expect.

In my opinion it is best avoided for that purpose and a better way to achieve what I was trying to do is

git fetch gitserver release_1:release_1

i.e. to fetch release_1 and call it release_1 locally. (It is source:dest, see https://git-scm.com/book/en/v2/Git-Internals-The-Refspec; just in case you'd like to give it a different name!)

You might want to use FETCH_HEAD at times though:-

git fetch gitserver bugfix1234
git cherry-pick FETCH_HEAD

might be a nice way of using bug fix number 1234 from your Git server, and leaving Git's garbage collection to dispose of the copy from the server once the fix has been cherry-picked onto your current branch. (I am assuming that there is a nice clean tagged commit containing the whole of the bug fix on the server!)

I think I know what you are asking for. Here is what you can do.

first get the height of the person say h meters.

if you can calculate the height of the camera from ground (using height if the person i.e. h) and get angles A and B using gyroscope or something from android then you can calculate the height of the object using the above formula.

Isn't this what you were looking for???

let me know if you need any explanation.

For properties for which css transition will affect, can use transitionend event, example for z-index:

$(".observed-element").on("webkitTransitionEnd transitionend", function(e) {_x000D_
  console.log("end", e);_x000D_
  alert("z-index changed");_x000D_
});_x000D_
_x000D_
$(".changeButton").on("click", function() {_x000D_
  console.log("click");_x000D_
  document.querySelector(".observed-element").style.zIndex = (Math.random() * 1000) | 0;_x000D_
});

.observed-element {_x000D_
  transition: z-index 1ms;_x000D_
  -webkit-transition: z-index 1ms;_x000D_
}_x000D_
div {_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  border: 1px solid;_x000D_
  position: absolute;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<button class="changeButton">change z-index</button>_x000D_
<div class="observed-element"></div>

You probably have allProviders typed as object[] as well. And property country does not exist on object. If you don't care about typing, you can declare both allProviders and countryProviders as Array<any>:

let countryProviders: Array<any>;
let allProviders: Array<any>;

If you do want static type checking. You can create an interface for the structure and use it:

interface Provider {
    region: string,
    country: string,
    locale: string,
    company: string
}

let countryProviders: Array<Provider>;
let allProviders: Array<Provider>;

Typically we would place one of these at or near the top of the script. Scripts that parse their command lines would do the redirection after parsing.

Send stdout to a file

exec > file

with stderr

exec > file                                                                      
exec 2>&1

append both stdout and stderr to file

exec >> file
exec 2>&1

As Jonathan Leffler mentioned in his comment:

exec has two separate jobs. The first one is to replace the currently executing shell (script) with a new program. The other is changing the I/O redirections in the current shell. This is distinguished by having no argument to exec.

while(something.hasnext())
do something...
   if(contains something to process){
      do something...
      break;
   }
}

Just use the break statement;

For eg:this just prints "Breaking..."

while (true) {
     if (true) {
         System.out.println("Breaking...");
         break;
     }
     System.out.println("Did this print?");
}

If it doesn't/wouldn't run on the CPU, it's a script to me. If an interpreter needs to run on the CPU below the program, then it's a script and a scripting language.

No reason to make it any more complicated than this?

Of course, in most (99%) of cases, it's clear whether a language is a scripting language. But consider that a VM can emulate the x86 instruction set, for example. Wouldn't this make the x86 bytecode a scripting language when run on a VM? What if someone was to write a compiler that would turn perl code into a native executable? In this case, I wouldn't know what to call the language itself anymore. It'd be the output that would matter, not the language.

Then again, I'm not aware of anything like this having been done, so for now I'm still comfortable calling interpreted languages scripting languages.

Deleting the .git folder may cause problems in your git repository. If you want to delete all your commit history but keep the code in its current state, it is very safe to do it as in the following:

1. Checkout

   git checkout --orphan latest_branch

2. Add all the files

   git add -A

3. Commit the changes

   git commit -am "commit message"

4. Delete the branch

   git branch -D main

5. Rename the current branch to main

   git branch -m main

6. Finally, force update your repository

   git push -f origin main

PS: this will not keep your old commit history around

Use this instead:

$('#save').click(function () {
    $('#mytable').find('input[type="checkbox"]:checked') //...
});

Let me explain you what the selector does: input[type="checkbox"] means that this will match each <input /> with type attribute type equals to checkbox After that: :checked will match all checked checkboxes.

You can loop over these checkboxes with:

$('#save').click(function () {
    $('#mytable').find('input[type="checkbox"]:checked').each(function () {
       //this is the current checkbox
    });
});

Here is demo in JSFiddle.

And here is a demo which solves exactly your problem http://jsfiddle.net/DuE8K/1/.

$('#save').click(function () {
    $('#mytable').find('tr').each(function () {
        var row = $(this);
        if (row.find('input[type="checkbox"]').is(':checked') &&
            row.find('textarea').val().length <= 0) {
            alert('You must fill the text area!');
        }
    });
});

For C89, use %lu and cast the value to unsigned long:

size_t foo;
...
printf("foo = %lu\n", (unsigned long) foo);

For C99 and later, use %zu:

size_t foo;
...
printf("foo = %zu\n", foo);

The underlying type of a variadic method function(Object... args) is function(Object[] args). Sun added varargs in this manner to preserve backwards compatibility.

So you should just be able to prepend extraVar to args and call String.format(format, args).

You can open the file again using vi helloworld.txt and then use cat /path/your_file to view it.

To set settings on the client:

HTH

Go to your git Directory then type the following command: rm -rf <Directory Name>

After Deleting the directory commit the changes by: git commit -m "Your Commit Message"

Then Simply push the changes on remote GIT directory: git push origin <Branch name>

This is the problem:

while(str.charAt(i)==ch)

That will keep going until it falls off the end... when i is the same as the length of the string, it will be asking for a character beyond the end of the string. You probably want:

while (i < str.length() && str.charAt(i) == ch)

You also need to set count to 0 at the start of each iteration of the bigger loop - the count resets, after all - and change

count = count + i;

to either:

count++;

... or get rid of count or i. They're always going to have the same value, after all. Personally I'd just use one variable, declared and initialized inside the loop. That's a general style point, in fact - it's cleaner to declare local variables when they're needed, rather than declaring them all at the top of the method.

However, then your program will loop forever, as this doesn't do anything useful:

str.substring(count);

Strings are immutable in Java - substring returns a new string. I think you want:

str = str.substring(count);

Note that this will still output "a2b2a2" for "aabbaa". Is that okay?

Could someone explain to me, how to call the move method with the variable RIGHT

>>> myMissile = MissileDevice(myBattery)  # looks like you need a battery, don't know what that is, you figure it out.
>>> myMissile.move(MissileDevice.RIGHT)

If you have programmed in any other language with classes, besides python, this sort of thing

class Foo:
    bar = "baz"

is probably unfamiliar. In python, the class is a factory for objects, but it is itself an object; and variables defined in its scope are attached to the class, not the instances returned by the class. to refer to bar, above, you can just call it Foo.bar; you can also access class attributes through instances of the class, like Foo().bar.

Im utterly baffled about what 'self' refers too,

>>> class Foo:
...     def quux(self):
...         print self
...         print self.bar
...     bar = 'baz'
...
>>> Foo.quux
<unbound method Foo.quux>
>>> Foo.bar
'baz'
>>> f = Foo()
>>> f.bar
'baz'
>>> f
<__main__.Foo instance at 0x0286A058>
>>> f.quux
<bound method Foo.quux of <__main__.Foo instance at 0x0286A058>>
>>> f.quux()
<__main__.Foo instance at 0x0286A058>
baz
>>>

When you acecss an attribute on a python object, the interpreter will notice, when the looked up attribute was on the class, and is a function, that it should return a "bound" method instead of the function itself. All this does is arrange for the instance to be passed as the first argument.

Use list comprehensions when the result needs to be iterated over multiple times, or where speed is paramount. Use generator expressions where the range is large or infinite.

See Generator expressions and list comprehensions for more info.

To do it in a generic JPA way using getter annotations, the example below works for me with Hibernate 3.5.4 and Oracle 11g. Note that the mapped getter and setter (getOpenedYnString and setOpenedYnString) are private methods. Those methods provide the mapping but all programmatic access to the class is using the getOpenedYn and setOpenedYn methods.

private String openedYn;

@Transient
public Boolean getOpenedYn() {
  return toBoolean(openedYn);
}

public void setOpenedYn(Boolean openedYn) {
  setOpenedYnString(toYesNo(openedYn));
}

@Column(name = "OPENED_YN", length = 1)
private String getOpenedYnString() {
  return openedYn;
}

private void setOpenedYnString(String openedYn) {
  this.openedYn = openedYn;
}

Here's the util class with static methods toYesNo and toBoolean:

public class JpaUtil {

    private static final String NO = "N";
    private static final String YES = "Y";

    public static String toYesNo(Boolean value) {
        if (value == null)
            return null;
        else if (value)
            return YES;
        else
            return NO;
    }

    public static Boolean toBoolean(String yesNo) {
        if (yesNo == null)
            return null;
        else if (YES.equals(yesNo))
            return true;
        else if (NO.equals(yesNo))
            return false;
        else
            throw new RuntimeException("unexpected yes/no value:" + yesNo);
    }
}

If you are using Carbon you can do the following. You could also format this date to set an Expire HTTP Header.

Carbon::parse('tomorrow midnight')->format(Carbon::RFC7231_FORMAT)

Under Windows 7 and XP, I can't get it to tell files vs. dirs on mapped drives. The following script:

@echo off
if exist c:\temp\data.csv echo data.csv is a file
if exist c:\temp\data.csv\ echo data.csv is a directory
if exist c:\temp\data.csv\nul echo data.csv is a directory
if exist k:\temp\nonexistent.txt echo nonexistent.txt is a file
if exist k:\temp\something.txt echo something.txt is a file
if exist k:\temp\something.txt\ echo something.txt is a directory
if exist k:\temp\something.txt\nul echo something.txt is a directory

produces:

data.csv is a file
something.txt is a file
something.txt is a directory
something.txt is a directory

So beware if your script might be fed a mapped or UNC path. The pushd solution below seems to be the most foolproof.

The sequences in postgresql are transaction safe. So you can use the

currval(sequence)

Quote:

currval

Return the value most recently obtained by nextval for this sequence in the current session. (An error is reported if nextval has never been called for this sequence in this session.) Notice that because this is returning a session-local value, it gives a predictable answer even if other sessions are executing nextval meanwhile.

we can be submit multiple updates together in JDBC to submit batch updates.

we can use Statement, PreparedStatement, and CallableStatement objects for bacth update with disable autocommit

addBatch() and executeBatch() functions are available with all statement objects to have BatchUpdate

here addBatch() method adds a set of statements or parameters to the current batch.

You can use a library called underscore js. It gives a nice wrapper on the bind method and is a much cleaner syntax as well. Letting you execute the function in the specified scope.

What is happening here?

1. Installing a package that checks updates for you.

2. Use this package to update all package versions in your package.json (-u is short for --updateAll).

3. Install all of the new versions of the packages.

It can be done several ways. I am mentioning 2 simple ways.

1. Very simple way as below:

   System.out.println("I\nam\na\nboy");
   

2. It can also be done with concatenation as below:

   System.out.println("I" + '\n' + "am" + '\n' + "a" + '\n' + "boy");
   

.NET 4

string.Join(",", arr)

.NET earlier

string.Join(",", Array.ConvertAll(arr, x => x.ToString()))

You need to add the package containing the executable pg_config.

A prior answer should have details you need: pg_config executable not found

From the help docs.

Python 2.7.12

>>> print range.__doc__
range(stop) -> list of integers
range(start, stop[, step]) -> list of integers

Return a list containing an arithmetic progression of integers.
range(i, j) returns [i, i+1, i+2, ..., j-1]; start (!) defaults to 0.
When step is given, it specifies the increment (or decrement).
For example, range(4) returns [0, 1, 2, 3].  The end point is omitted!
These are exactly the valid indices for a list of 4 elements.

>>> print xrange.__doc__
xrange(stop) -> xrange object
xrange(start, stop[, step]) -> xrange object

Like range(), but instead of returning a list, returns an object that
generates the numbers in the range on demand.  For looping, this is 
slightly faster than range() and more memory efficient.

Python 3.5.2

>>> print(range.__doc__)
range(stop) -> range object
range(start, stop[, step]) -> range object

Return an object that produces a sequence of integers from start (inclusive)
to stop (exclusive) by step.  range(i, j) produces i, i+1, i+2, ..., j-1.
start defaults to 0, and stop is omitted!  range(4) produces 0, 1, 2, 3.
These are exactly the valid indices for a list of 4 elements.
When step is given, it specifies the increment (or decrement).

>>> print(xrange.__doc__)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'xrange' is not defined

Difference is apparent. In Python 2.x, range returns a list, xrange returns an xrange object which is iterable.

In Python 3.x, range becomes xrange of Python 2.x, and xrange is removed.

The reason is one servlet container is already running on port 8080 and you are trying to run another one on port 8080.

• 1. Check what processes are running at available ports.

     • For Windows :

     • netstat -ao |find /i "listening"

     OR

     • netstat -ano | find "8080" (Note: 8080 is port fail to start)

• 2. Now try to reLaunch or stop your application.

     • To relaunch: you can press this button

  

  • To stop in windows:

  Taskkill /F /IM 6592 Note: Mention correct Process Id

  

  right click on the console and select terminate/disconnect all

  • Go to Task Manager and end Java(tm) platform se binary

  

  What is java(tm) platform se binary(Search in google

Another option is :

Go to application.properties file set server.port=0. This will cause Spring Boot to use a random free port every time it starts.

I use like this using React Component state:

<input type="text" name='value' value={this.state.value} onChange={(e) => this.handleChange(e)} />

handleChange(e){
   this.setState({[e.target.name]: e.target.value})
}`

I find the easiest way is to double up on the quotes to handle a quote.

Worksheets("Sheet1").Range("A1").Formula = "IF(Sheet1!A1=0,"""",Sheet1!A1)" 

Some people like to use CHR(34)*:

Worksheets("Sheet1").Range("A1").Formula = "IF(Sheet1!A1=0," & CHR(34) & CHR(34) & ",Sheet1!A1)" 

*Note: CHAR() is used as an Excel cell formula, e.g. writing "=CHAR(34)" in a cell, but for VBA code you use the CHR() function.

In Android Studio, go to app -> src -> main -> java -> com.example.username.projectname

Right click on com.example.username.projectname -> Activity -> ActivityType

Fill in the details of the New Android Activity and click Finish.

Viola! new activity added to the existing project.

Apart from other answer There are calculator provided by Youtube to check your usage. It is good to identify your usage. https://developers.google.com/youtube/v3/determine_quota_cost

This is quite simple the way I resolved this problem:

1. open SQL Server
2. right click on database (you want to be backup)
3. select properties
4. select permissions
5. select your database role (local or cloud)
6. in the you bottom you will see explicit permissions table
7. find " backup database " permission and click Grant permission .

your problem is resolved .

This is just a sample code, but it may help you get on your way:

Public Sub testIt()
    Workbooks("Workbook2").Activate
    ActiveWorkbook.Sheets("Sheet2").Activate
    ActiveSheet.Range("B3").Select
    ActiveCell.EntireRow.Insert
End Sub

I am assuming that you can open the book (called Workbook2 in the example).

I think (but I'm not sure) you can squash all this in a single line of code:

    Workbooks("Workbook2").Sheets("Sheet2").Range("B3").EntireRow.Insert

This way you won't need to activate the workbook (or sheet or cell)... Obviously, the book has to be open.

Instead of using the conditions syntax from Rails 2, use Rails 4's where method instead:

def self.search(search, page = 1 )
  wildcard_search = "%#{search}%"

  where("name ILIKE :search OR postal_code LIKE :search", search: wildcard_search)
    .page(page)
    .per_page(5)
end

NOTE: the above uses parameter syntax instead of ? placeholder: these both should generate the same sql.

def self.search(search, page = 1 )
  wildcard_search = "%#{search}%"

  where("name ILIKE ? OR postal_code LIKE ?", wildcard_search, wildcard_search)
    .page(page)
    .per_page(5)
end

NOTE: using ILIKE for the name - postgres case insensitive version of LIKE

I'm the creator of Restangular.

You can take a look at this CRUD example to see how you can PUT/POST/GET elements without all that URL configuration and $resource configuration that you need to do. Besides it, you can then use nested resources without any configuration :).

Check out this plunkr example:

http://plnkr.co/edit/d6yDka?p=preview

You could also see the README and check the documentation here https://github.com/mgonto/restangular

If you need some feature that's not there, just create an issue. I usually add features asked within a week, as I also use this library for all my AngularJS projects :)

Hope it helps!

Simply parsing the JSON and comparing the two objects is not enough because it wouldn't be the exact same object references (but might be the same values).

You need to do a deep equals.

From http://threebit.net/mail-archive/rails-spinoffs/msg06156.html - which seems the use jQuery.

Object.extend(Object, {
   deepEquals: function(o1, o2) {
     var k1 = Object.keys(o1).sort();
     var k2 = Object.keys(o2).sort();
     if (k1.length != k2.length) return false;
     return k1.zip(k2, function(keyPair) {
       if(typeof o1[keyPair[0]] == typeof o2[keyPair[1]] == "object"){
         return deepEquals(o1[keyPair[0]], o2[keyPair[1]])
       } else {
         return o1[keyPair[0]] == o2[keyPair[1]];
       }
     }).all();
   }
});

Usage:

var anObj = JSON.parse(jsonString1);
var anotherObj= JSON.parse(jsonString2);

if (Object.deepEquals(anObj, anotherObj))
   ...

You can also choose to serialize your data and then visualize it in D3.js, as done here: Use Python & Pandas to Create a D3 Force Directed Network Diagram (It comes with a jupyter notebook as well!)

Here is the gist. You serialize your graph data in this format:

import json
json_data = {
  "nodes":[
    {"name":"Myriel","group":1},
    {"name":"Napoleon","group":1},
    {"name":"Mlle.Baptistine","group":1},
    {"name":"Mme.Magloire","group":1},
    {"name":"CountessdeLo","group":1},
  ],
  "links":[
    {"source":1,"target":0,"value":1},
    {"source":2,"target":0,"value":8},
    {"source":3,"target":0,"value":10},
    {"source":3,"target":2,"value":6},
    {"source":4,"target":0,"value":1},
    {"source":5,"target":0,"value":1},
  ]
}
filename_out = 'graph_data.json'
json_out = open(filename_out,'w')
json_out.write(json_data)
json_out.close()

Then you load the data in with d3.js:

d3.json("pcap_export.json", drawGraph);

For the routine drawGraph I refer you to the link, however.

I have figured out a solution to this problem. We can build a Function or View with "rendered" sql in a stored procedure that can then be executed as normal.

1.Create another sproc

CREATE PROCEDURE [dbo].[usp_FunctionBuilder]
DECLARE @outerSql VARCHAR(MAX)
DECLARE @innerSql VARCHAR(MAX)

2.Build the dynamic sql that you want to execute in your function (Example: you could use a loop and union, you could read in another sproc, use if statements and parameters for conditional sql, etc.)

SET @innerSql = 'your sql'

3.Wrap the @innerSql in a create function statement and define any external parameters that you have used in the @innerSql so they can be passed into the generated function.

SET @outerSql = 'CREATE FUNCTION [dbo].[fn_GeneratedFunction] ( @Param varchar(10))
RETURNS TABLE
AS
RETURN
' + @innerSql;


EXEC(@outerSql)

This is just pseudocode but the solution solves many problems such as linked server limitations, parameters, dynamic sql in function, dynamic server/database/table name, loops, etc.

You will need to tweak it to your needs, (Example: changing the return in the function)

Since you're looking for the ability to shoehorn binary data into a strictly text-based and very limited format, I think Base64's overhead is minimal compared to the convenience you're expecting to maintain with JSON. If processing power and throughput is a concern, then you'd probably need to reconsider your file formats.

For people who find this via search engines, you do not need VBA. You can just:

1.) select the query or table with your mouse
2.) click export data from the ribbon
3.) click excel from the export subgroup
4.) follow the wizard to select the output file and location.

If you want to ask based on condition:

var ask = true
window.onbeforeunload = function (e) {
    if(!ask) return null
    e = e || window.event;
    //old browsers
    if (e) {e.returnValue = 'Sure?';}
    //safari, chrome(chrome ignores text)
    return 'Sure?';
};

To check if the property exists and if it's null too, you can use the function property_exists().

Docs: http://php.net/manual/en/function.property-exists.php

As opposed with isset(), property_exists() returns TRUE even if the property has the value NULL.

bool property_exists ( mixed $class , string $property )

Example:

if (property_exists($testObject, $property)) {
    //do something
}

SQL Error: ORA-30926: unable to get a stable set of rows in the source tables
30926. 00000 -  "unable to get a stable set of rows in the source tables"
*Cause:    A stable set of rows could not be got because of large dml
           activity or a non-deterministic where clause.
*Action:   Remove any non-deterministic where clauses and reissue the dml.

This Error occurred for me because of duplicate records(16K)

I tried with unique it worked .

but again when I tried merge without unique same proble occurred Second time it was due to commit

after merge if commit is not done same Error will be shown.

Without unique, Query will work if commit is given after each merge operation.

Try using the type attribute selector to find buttons (maybe this'll fix it too):

input[type=button]
{
  background-color: #E3E1B8; 
}

input[type=button]:hover
{
  background-color: #46000D
}

If you are also trying to gzip dynamic pages (like aspx) and it isnt working, its probably because the option is not enabled (you need to install the Dynamic Content Compression module using Windows Features):

http://support.esri.com/en/knowledgebase/techarticles/detail/38616

I had this issue when I was using homebrew. Here is the solution from Issue #26900

python -m pip install --upgrade --force pip

You should possibly make data a keyword parameter with a default value of empty dictionary:

class DHT:
    def __init__(self, data=dict()):
        self.data['one'] = '1'
        self.data['two'] = '2'
        self.data['three'] = '3'
    def showData(self):
        print(self.data)

if __name__ == '__main__': 
    DHT().showData()

Use below bash command to locate all virtual env in your system. You can modify the command according to your need to get in your desired format.

locate --regex "bin/activate"$ | sed 's/bin\/activate$//'

What worked for me was downgrading from EF 6.1.3 to EF 6.1.1.

In Visual Studios 2012+ head over to:

Tools - Nuget Package Manager - Package Manager Console`

Then enter:

Install-Package EntityFramework.SqlServerCompact -Version 6.1.1

I did not have to uninstall EF 6.1.3 first because the command above already does that.

In addition, I don't know if it did something, but I also installed SQL Server CE in my project.

Here's the link to the solution I found:

http://www.itorian.com/2014/11/no-entity-framework-provider-found-for.html

Command:

foo >> output.txt 2>&1

appends to the output.txt file, without replacing the content.

Try this:

word = "habit"
findchar = 'b"
replacechar = ""
charactercount = len(word) - len(replace(word,findchar,replacechar))

Maybe you can create an array like this:

     var myList = new Array();
     myList.push('Hello');
     myList.push('bye');

     for (var i = 0; i < myList .length; i ++ ){
        window.console.log(myList[i]);
     }

I have noticed that when using type="image/vnd.microsoft.icon", the favicon fails to appear when the browser is not connected to the internet. But type="image/x-icon" works whether the browser can connect to the internet, or not. When developing, at times I am not connected to the internet.

If you're in a client-side web environment, the new auth2 javascript API contains a much-needed getBasicProfile() function, which returns the user's name, email, and image URL.

https://developers.google.com/identity/sign-in/web/reference#googleusergetbasicprofile

I actually needed to do something pretty similar just now

Ended up writing a function which returns a list of tuples indicating the start and end of each month between two sets of dates so I could write some SQL queries off the back of it for monthly totals of sales etc.

I'm sure it can be improved by someone who knows what they're doing but hope it helps...

The returned value look as follows (generating for today - 365days until today as an example)

[   (datetime.date(2013, 5, 1), datetime.date(2013, 5, 31)),
    (datetime.date(2013, 6, 1), datetime.date(2013, 6, 30)),
    (datetime.date(2013, 7, 1), datetime.date(2013, 7, 31)),
    (datetime.date(2013, 8, 1), datetime.date(2013, 8, 31)),
    (datetime.date(2013, 9, 1), datetime.date(2013, 9, 30)),
    (datetime.date(2013, 10, 1), datetime.date(2013, 10, 31)),
    (datetime.date(2013, 11, 1), datetime.date(2013, 11, 30)),
    (datetime.date(2013, 12, 1), datetime.date(2013, 12, 31)),
    (datetime.date(2014, 1, 1), datetime.date(2014, 1, 31)),
    (datetime.date(2014, 2, 1), datetime.date(2014, 2, 28)),
    (datetime.date(2014, 3, 1), datetime.date(2014, 3, 31)),
    (datetime.date(2014, 4, 1), datetime.date(2014, 4, 30)),
    (datetime.date(2014, 5, 1), datetime.date(2014, 5, 31))]

Code as follows (has some debug stuff which can be removed):

#! /usr/env/python
import datetime

def gen_month_ranges(start_date=None, end_date=None, debug=False):
    today = datetime.date.today()
    if not start_date: start_date = datetime.datetime.strptime(
        "{0}/01/01".format(today.year),"%Y/%m/%d").date()  # start of this year
    if not end_date: end_date = today
    if debug: print("Start: {0} | End {1}".format(start_date, end_date))

This will help you make your own hover class for bootstrap:

CSS:

/* Hover dropdown */
.hover_drop_down.input-group-btn ul.dropdown-menu{margin-top: 0px;}/*To avoid unwanted close*/
.hover_drop_down.btn-group ul.dropdown-menu{margin-top:2px;}/*To avoid unwanted close*/
.hover_drop_down:hover ul.dropdown-menu{
   display: block;
}

Margins are set to avoid unwanted close and they are optional.

HTML:

<div class="btn-group hover_drop_down">
  <button type="button" class="btn btn-default" data-toggle="dropdown"></button>
  <ul class="dropdown-menu" role="menu">
    ...
  </ul>
</div>

Don't forget to remove the button attribute data-toggle="dropdown" if you want to remove onclick open, and this also will work when input is append with dropdown.

An example of use :

You consume many classes that have a commun property 'CreationDate' :

public class Contact
{
    // some properties

    public DateTime CreationDate { get; set; }        
}

public class Company
{
    // some properties

    public DateTime CreationDate { get; set; }

}

public class Opportunity
{
    // some properties

    public DateTime CreationDate { get; set; }

}

If you write a commun method that retrieves the value of the 'CreationDate' Property, you'd have to use reflection:

    static DateTime RetrieveValueOfCreationDate(Object item)
    {
        return (DateTime)item.GetType().GetProperty("CreationDate").GetValue(item);
    }

With the 'dynamic' concept, your code is much more elegant :

    static DateTime RetrieveValueOfCreationDate(dynamic item)
    {
        return item.CreationDate;
    }

You can get country from IP address with this location API

Code

    echo file_get_contents('https://ipapi.co/8.8.8.8/country/');

Response

   US 

Here's a fiddle. Response is text when you query a specific field e.g. country here. No decoding needed, just plug it into your code.

P.S. If you want all the fields e.g. https://ipapi.co/8.8.8.8/json/, the response is JSON.

This is one of those simple things that doesn't (AFAIK) exist in the standard Java API. It's easy enough to write your own.

Other answers are perfectly fine, but here's one with some for-each syntactic sugar.

int someArray[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
int sum = 0;

for (int i : someArray)
    sum += i;

Also, an example of array summation is even shown in the Java 7 Language Specification. The example is from Section 10.4 - Array Access.

class Gauss {
    public static void main(String[] args) {
        int[] ia = new int[101];
        for (int i = 0; i < ia.length; i++) ia[i] = i;
        int sum = 0;
        for (int e : ia) sum += e;
        System.out.println(sum);
    }
}

You can use obj.constructor.name to check the "class" of an object https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/name#Function_names_in_classes

For Example

var error = new Error("ValidationError");
console.log(error.constructor.name);

The above line will log "Error" which is the class name of the object. This could be used with any classes in javascript, if the class is not using a property that goes by the name "name"

(Posting in case someone might have a use of it).

I was looking for a solution for a problem a bit more sophisticated than OP - replacing EVERY occurrence of something with the number by same thing with incremented number

E.g. Replacing something like this:

<row id="1" />
<row id="2" />
<row id="1" />
<row id="3" />
<row id="1" />

By this:

<row id="2" />
<row id="3" />
<row id="2" />
<row id="4" />
<row id="2" />

Couldnt find the solution online so I wrote my own script in groovy (a bit ugly but does the job):

 /**
 * <p> Finds words that matches template and increases them by 1.
 * '_' in word template represents number.
 *
 * <p> E.g. if template equals 'Row="_"', then:
 * ALL Row=0 will be replaced by Row="1"
 * All Row=1 will be replaced by Row="2"
 * <p> Warning - your find template might not work properly if _ is the last character of it
 * etc.
 * <p> Requirments:
 * - Original text does not contain tepmlate string
 * - Only numbers in non-disrupted sequence are incremented and replaced
 * (i.e. from example below, if Row=4 exists in original text, but Row=3 not, than Row=4 will NOT be 
 * replaced by Row=5)
 */
def replace_inc(String text, int startingIndex, String findTemplate) {
    assert findTemplate.contains('_') : 'search template needs to contain "_" placeholder'
    assert !(findTemplate.replaceFirst('_','').contains('_')) : 'only one "_" placeholder is allowed'
    assert !text.contains('_____') : 'input text should not contain "______" (5 underscores)'
    while (true) {
        findString = findTemplate.replace("_",(startingIndex).toString())
        if (!text.contains(findString)) break;
        replaceString = findTemplate.replace("_", "_____"+(++startingIndex).toString())
        text = text.replaceAll(findString, replaceString)
    }
    return text.replaceAll("_____","") // get rid of '_____' character
}

// input
findTemplate = 'Row="_"'
path = /C:\TEMP\working_copy.txt/
startingIndex = 0

// do stuff
f = new File(path)
outText = replace_inc(f.text,startingIndex,findTemplate)
println "Results \n: " + outText
f.withWriter { out -> out.println outText }
println "Results written to $f"

Accept attribute was introduced in the RFC 1867, intending to enable file-type filtering based on MIME type for the file-select control. But as of 2008, most, if not all, browsers make no use of this attribute. Using client-side scripting, you can make a sort of extension based validation, for submit data of correct type (extension).

Other solutions for advanced file uploading require Flash movies like SWFUpload or Java Applets like JUpload.

It probably makes sense to emphasize one thing that the most have missed, which may prevent immediate understanding. When you type python in terminal you don't normally provide a full path. Instead, the executable is up looked in PATH environment variable. In turn, when you want to execute a Python program directly, /path/to/app.py, one must tell the shell what interpreter to use (via the hashbang, what the other contributors are explaining above).

Hashbang expects full path to an interpreter. Thus to run your Python program directly you have to provide full path to Python binary which varies significantly, especially considering a use of virtualenv. To address portability the trick with /usr/bin/env is used. The latter is originally intended to alter environment in-place and run a command in it. When no alteration is provided it runs the command in current environment, which effectively results in the same PATH lookup which does the trick.

If you want to access the string as a non-optional, you should use Ryan's Answer, but if you only care about the non-emptiness of the string, my preferred shorthand for this is

if stringA?.isEmpty == false {
    ...blah blah
}

Since == works fine with optional booleans, I think this leaves the code readable without obscuring the original intention.

If you want to check the opposite: if the string is nil or "", I prefer to check both cases explicitly to show the correct intention:

if stringA == nil || stringA?.isEmpty == true {
    ...blah blah
}

Fixed it with:

element.scrollIntoView({ behavior: 'smooth', block: 'nearest', inline: 'start' })

see: https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollIntoView

Two simple options occur:

• Use charAt() repeatedly
• Use indexOf() repeatedly

For example:

public static int nthIndexOf(String text, char needle, int n)
{
    for (int i = 0; i < text.length(); i++)
    {
        if (text.charAt(i) == needle)
        {
            n--;
            if (n == 0)
            {
                return i;
            }
        }
    }
    return -1;
}

That may well not perform as well as using indexOf repeatedly, but it's possibly simpler to get right.

This worked for me:

pip install psycopg2-binary

:g/^M/s// /g

If you type ^M using Shift+6 Caps+M it won't accept.

You need to type ctrl+v ctrl+m.

In most of the modern single page applications, we indeed have to store the token somewhere on the client side (most common use case - to keep the user logged in after a page refresh).

There are a total of 2 options available: Web Storage (session storage, local storage) and a client side cookie. Both options are widely used, but this doesn't mean they are very secure.

Tom Abbott summarizes well the JWT sessionStorage and localStorage security:

Web Storage (localStorage/sessionStorage) is accessible through JavaScript on the same domain. This means that any JavaScript running on your site will have access to web storage, and because of this can be vulnerable to cross-site scripting (XSS) attacks. XSS, in a nutshell, is a type of vulnerability where an attacker can inject JavaScript that will run on your page. Basic XSS attacks attempt to inject JavaScript through form inputs, where the attacker puts <script>alert('You are Hacked');</script> into a form to see if it is run by the browser and can be viewed by other users.

To prevent XSS, the common response is to escape and encode all untrusted data. React (mostly) does that for you! Here's a great discussion about how much XSS vulnerability protection is React responsible for.

But that doesn't cover all possible vulnerabilities! Another potential threat is the usage of JavaScript hosted on CDNs or outside infrastructure.

Here's Tom again:

Modern web apps include 3rd party JavaScript libraries for A/B testing, funnel/market analysis, and ads. We use package managers like Bower to import other peoples’ code into our apps.

What if only one of the scripts you use is compromised? Malicious JavaScript can be embedded on the page, and Web Storage is compromised. These types of XSS attacks can get everyone’s Web Storage that visits your site, without their knowledge. This is probably why a bunch of organizations advise not to store anything of value or trust any information in web storage. This includes session identifiers and tokens.

Therefore, my conclusion is that as a storage mechanism, Web Storage does not enforce any secure standards during transfer. Whoever reads Web Storage and uses it must do their due diligence to ensure they always send the JWT over HTTPS and never HTTP.

Just want to add Matas' answer. Maybe it's obvious, but I've searched for a long time to figure out that the variable is accessible only inside the BEGIN-END construction, so if you need to use it in some code later, you need to put this code inside the BEGIN-END block.

Note that these blocks can be nested:

DECLARE x NUMBER;
BEGIN
    SELECT PK INTO x FROM table1 WHERE col1 = 'test';

    DECLARE y NUMBER;
    BEGIN
        SELECT PK INTO y FROM table2 WHERE col2 = x;

        INSERT INTO table2 (col1, col2)
        SELECT y,'text'
        FROM dual
        WHERE exists(SELECT * FROM table2);

        COMMIT;
    END;
END;

calloc is generally malloc+memset to 0

It is generally slightly better to use malloc+memset explicitly, especially when you are doing something like:

ptr=malloc(sizeof(Item));
memset(ptr, 0, sizeof(Item));

That is better because sizeof(Item) is know to the compiler at compile time and the compiler will in most cases replace it with the best possible instructions to zero memory. On the other hand if memset is happening in calloc, the parameter size of the allocation is not compiled in in the calloc code and real memset is often called, which would typically contain code to do byte-by-byte fill up until long boundary, than cycle to fill up memory in sizeof(long) chunks and finally byte-by-byte fill up of the remaining space. Even if the allocator is smart enough to call some aligned_memset it will still be a generic loop.

One notable exception would be when you are doing malloc/calloc of a very large chunk of memory (some power_of_two kilobytes) in which case allocation may be done directly from kernel. As OS kernels will typically zero out all memory they give away for security reasons, smart enough calloc might just return it withoud additional zeroing. Again - if you are just allocating something you know is small, you may be better off with malloc+memset performance-wise.

Do a regex "Search" for \t (backslash-t, a tab), and replace with four spaces.

Either the main menu, or lower-right status-bar spacing menu does the same thing, with less work.

To run tests with node/npm without installing Mocha globally, you can do this:

• Install Mocha locally to your project (npm install mocha --save-dev)

• Optionally install an assertion library (npm install chai --save-dev)

• In your package.json, add a section for scripts and target the mocha binary

"scripts": {
  "test": "node ./node_modules/mocha/bin/mocha"
}

• Put your spec files in a directory named /test in your root directory

• In your spec files, import the assertion library

var expect = require('chai').expect;

• You don't need to import mocha, run mocha.setup, or call mocha.run()

• Then run the script from your project root:

npm test

As karim79 mentioned, the first is the most concise. However I could argue that the second is more understandable as it is not obvious/known to some Javascript/jQuery programmers that non-zero/false values are evaluated to true in if-statements. And because of that, the third method is incorrect.

Try with:

$end = date('Y-m-d', strtotime('+5 years'));

In Spring boot, /META-INF/resources/, /resources/, static/ and public/ directories are available to serve static contents.

So you can create a static/ or public/ directory under resources/ directory and put your static contents there. And they will be accessible by: http://localhost:8080/your-file.ext. (assuming the server.port is 8080)

You can customize these directories using spring.resources.static-locations in the application.properties.

For example:

spring.resources.static-locations=classpath:/custom/

Now you can use custom/ folder under resources/ to serve static files.

Update:

This is also possible using java config:

@Configuration
public class StaticConfig implements WebMvcConfigurer {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/static/**").addResourceLocations("classpath:/custom/");
    }
}

This confugration maps contents of custom directory to the http://localhost:8080/static/** url.

Use Access's VBA function Replace(text, find, replacement):

Dim result As String

result = Replace("Some sentence containing Avenue in it.", "Avenue", "Ave")

You could have a dictionary where the entries are a list of other dictionaries:

fruit_dict = dict()
fruit_dict['banana'] = [{'yellow': 24}]
fruit_dict['apple'] = [{'red': 12}, {'green': 14}]
print fruit_dict

Output:

{'banana': [{'yellow': 24}], 'apple': [{'red': 12}, {'green': 14}]}

Edit: As eumiro pointed out, you could use a dictionary of dictionaries:

fruit_dict = dict()
fruit_dict['banana'] = {'yellow': 24}
fruit_dict['apple'] = {'red': 12, 'green': 14}
print fruit_dict

Output:

{'banana': {'yellow': 24}, 'apple': {'green': 14, 'red': 12}}

There's a builtin method find on string objects.

s = "Happy Birthday"
s2 = "py"

print(s.find(s2))

Python is a "batteries included language" there's code written to do most of what you want already (whatever you want).. unless this is homework :)

find returns -1 if the string cannot be found.

I have posted this answer as this question was viewed most and this server side code was written in VS 2015 in C# for sending push notification either single device based on device id or subscribed topic to Xamarin Android app

I've had the same problem with you.

cd to ../etc/ then use ls to make sure your "paths" file is in , vim paths, add "/usr/local/bin" at the end of the file.

Heres a lil program I was using to capitalize each first letter word in every subfolder of a parent directory.

private void capitalize(String string)
{
    List<String> delimiters = new ArrayList<>();
    delimiters.add(" ");
    delimiters.add("_");

    File folder = new File(string);
    String name = folder.getName();
    String[] characters = name.split("");

    String newName = "";
    boolean capitalizeNext = false;

    for (int i = 0; i < characters.length; i++)
    {
        String character = characters[i];

        if (capitalizeNext || i == 0)
        {
            newName += character.toUpperCase();
            capitalizeNext = false;
        }
        else
        {
            if (delimiters.contains(character)) capitalizeNext = true;
            newName += character;
        }
    }

    folder.renameTo(new File(folder.getParent() + File.separator + newName));
}

You've already discovered the simplest way to specify a shallow clone in Git-SVN, by specifying the SVN revision number that you want to start your clone at ( -r$REV:HEAD).

For example: git svn clone -s -r1450:HEAD some/svn/repo

Git's data structure is based on pointers in a directed acyclic graph (DAG), which makes it trivial to walk back n commits. But in SVN ( and therefore in Git-SVN) you will have to find the revision number yourself.

I go with

we can change angular CLI favicon icon. we have to put icon file in "assets" folder and give that path in index.html.

<link rel="icon" type="image/x-icon" href="./assets/images/favicon.png"> It's work for me.

I suggest using PhantomJS. For more information, you may visit the Phantom Official Website.

As far as I know PhantomJS works only with Firefox...

After downloading PhantomJs.exe you need to import it to your project as you can see in the picture below PhantomJS.

I have placed mine inside: common ? Library ? phantomjs.exe

Now all you have to do inside your Selenium code is to change the line

browser = webdriver.Firefox()

To something like

import os
path2phantom = os.getcwd() + "\common\Library\phantomjs.exe"
browser = webdriver.PhantomJS(path2phantom)

The path to PhantomJS may be different... change as you like :)

This hack worked for me, and I'm pretty sure it will work for u too ;)

This may work for you:

select t1.*
from table t1
join (select t2.Chromosome, t2.Locus
    from table2
    group by t2.Chromosome, t2.Locus
    having count(*) > 1) u on u.Chromosome = t1.Chromosome and u.Locus = t1.Locus

TextBoxFor: It will render like text input html element corresponding to specified expression. In simple word it will always render like an input textbox irrespective datatype of the property which is getting bind with the control.

EditorFor: This control is bit smart. It renders HTML markup based on the datatype of the property. E.g. suppose there is a boolean property in model. To render this property in the view as a checkbox either we can use CheckBoxFor or EditorFor. Both will be generate the same markup.

What is the advantage of using EditorFor?

As we know, depending on the datatype of the property it generates the html markup. So suppose tomorrow if we change the datatype of property in the model, no need to change anything in the view. EditorFor control will change the html markup automatically.

Sets have no order, but if you still want to get the first element you can use the following:

<c:forEach var="attachment" items="${attachments}" end="0">
     <c:out value="${attachment.id} />
</c:forEach>

Similar to answer by @Jeff_Alieffson, but not relying on default Locale:

Use DecimalFormatSymbols for explicit locale:

DecimalFormatSymbols decimalFormatSymbols  = DecimalFormatSymbols.getInstance(new Locale("ru", "RU"));

Or explicit separator symbols:

DecimalFormatSymbols decimalFormatSymbols = new DecimalFormatSymbols();
decimalFormatSymbols.setDecimalSeparator('.');
decimalFormatSymbols.setGroupingSeparator(' ');

Then:

new DecimalFormat("#,##0.00", decimalFormatSymbols).format(new BigDecimal("12345"));

Result:

12 345.00

You can either use tsc --declaration fileName.ts like Ryan describes, or you can specify declaration: true under compilerOptionsin your tsconfig.json assuming you've already had a tsconfig.json under your project.

Try this if you are using jquery version >=1.9,

var browser;
jQuery.uaMatch = function (ua) {
    ua = ua.toLowerCase();

    var match = /(chrome)[ \/]([\w.]+)/.exec(ua) ||
        /(webkit)[ \/]([\w.]+)/.exec(ua) ||
        /(opera)(?:.*version|)[ \/]([\w.]+)/.exec(ua) ||
        /(msie) ([\w.]+)/.exec(ua) || 
        ua.indexOf("compatible") < 0 && /(mozilla)(?:.*? rv:([\w.]+)|)/.exec(ua) ||
       /(Trident)[\/]([\w.]+)/.exec(ua) || [];

    return {
        browser: match[1] || "",
        version: match[2] || "0"
    };
};
// Don't clobber any existing jQuery.browser in case it's different
if (!jQuery.browser) {
    matched = jQuery.uaMatch(navigator.userAgent);
    browser = {};

    if (matched.browser) {
        browser[matched.browser] = true;
        browser.version = matched.version;
    }

    // Chrome is Webkit, but Webkit is also Safari.
    if (browser.chrome) {
        browser.webkit = true;
    } else if (browser.webkit) {
        browser.safari = true;
    }

    jQuery.browser = browser;
}

If using jQuery version <1.9 ($.browser was removed in jQuery 1.9) use the following code instead:

$('.myClass').on('click', function (event) {
    if ($.browser.msie) {
        alert($.browser.version);
    }
});

Use DATE(NOW()) to compare dates

DATE(NOW()) will give you the date part of current date and DATE(duedate) will give you the date part of the due date. then you can easily compare the dates

So you can compare it like

DATE(NOW()) = DATE(duedate)

OR

DATE(duedate) = CURDATE()

What back-end? If JAVA then you can use REST with Java (JAX-RS) using Jersey.

On the Android side you can use this simple RestClient to work with that REST service.

For JSON <--> Object mapping on both sides (Android, Java back-end) you can use GSON.

Since sockstat wasn't natively installed on my machine I hacked up stanwise's answer to use netstat instead..

netstat -nlp | grep -E "[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\:2000" | awk '{print $7}' | sed -e "s/\/.*//g""

It seems important to exactly match the format of the ISO string for TryParseExact to work. I guess Exact is Exact and this answer is obvious to most but anyway...

In my case, Reb.Cabin's answer doesn't work as I have a slightly different input as per my "value" below.

Value: 2012-08-10T14:00:00.000Z

There are some extra 000's in there for milliseconds and there may be more.

However if I add some .fff to the format as shown below, all is fine.

Format String: @"yyyy-MM-dd\THH:mm:ss.fff\Z"

In VS2010 Immediate Window:

DateTime.TryParseExact(value,@"yyyy-MM-dd\THH:mm:ss.fff\Z", CultureInfo.InvariantCulture,DateTimeStyles.AssumeUniversal, out d);

true

You may have to use DateTimeStyles.AssumeLocal as well depending upon what zone your time is for...

Thanks Darin, For me, to be able to post to the create method, It only worked after I modified the BindModel code to :

public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
    var displayFormat = bindingContext.ModelMetadata.DisplayFormatString;
    var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);

    if (!string.IsNullOrEmpty(displayFormat) && value != null)
    {
        DateTime date;
        displayFormat = displayFormat.Replace("{0:", string.Empty).Replace("}", string.Empty);
        // use the format specified in the DisplayFormat attribute to parse the date
         if (DateTime.TryParse(value.AttemptedValue, CultureInfo.GetCultureInfo("en-GB"), DateTimeStyles.None, out date))
        {
            return date;
        }
        else
        {
            bindingContext.ModelState.AddModelError(
                bindingContext.ModelName,
                string.Format("{0} is an invalid date format", value.AttemptedValue)
            );
        }
    }

    return base.BindModel(controllerContext, bindingContext);
}

They can't be initialised inside the class, but they can be initialised outside the class, in a source file:

Update

I've just noticed the first line of your question - you don't want to make those functions static, you want to make them const. Making them static means that they are no longer associated with an object (so they can't access any non-static members), and making the data static means it will be shared with all objects of this type. This may well not be what you want. Making them const simply means that they can't modify any members, but can still access them.

You can use kill -0 for checking whether a particular pid is running or not.

Assuming, you have list of pid numbers in a file called pid in pwd

while true;
do 
    if [ -s pid ] ; then
        for pid in `cat pid`
        do  
            echo "Checking the $pid"
            kill -0 "$pid" 2>/dev/null || sed -i "/^$pid$/d" pid
        done
    else
        echo "All your process completed" ## Do what you want here... here all your pids are in finished stated
        break
    fi
done

Make sure you select the function that needs to be executed. See screenshot:

No real answer to your question but:
Generally relying on the clients IP address is in my opinion not a good practice as it is not usable to identify clients in a unique fashion.

Problems on the road are that there are quite a lot scenarios where the IP does not really align to a client:

• Proxy/Webfilter (mangle almost everything)
• Anonymizer network (no chance here either)
• NAT (an internal IP is not very useful for you)
• ...

I cannot offer any statistics on how many IP addresses are on average reliable but what I can tell you that it is almost impossible to tell if a given IP address is the real clients address.

I found that pathlib module also supports this.

from pathlib import Path
>>> Path.home()
WindowsPath('C:/Users/XXX')

Use the keySet() method to return a set with all the keys of a Map.

If you want to keep your Map ordered you can use a TreeMap.

Or use the XmlSerializer class.

XmlSerializer xs = new XmlSerializer(objectType);
obj = xs.Deserialize(new StringReader(yourXmlString));

Using plyr::ldply there is roughly a 50% speed increase by enabling the .parallel option while reading 400 csv files roughly 30-40 MB each. Example includes a text progress bar.

library(plyr)
library(data.table)
library(doSNOW)

csv.list <- list.files(path="t:/data", pattern=".csv$", full.names=TRUE)

cl <- makeCluster(4)
registerDoSNOW(cl)

pb <- txtProgressBar(max=length(csv.list), style=3)
pbu <- function(i) setTxtProgressBar(pb, i)
dt <- setDT(ldply(csv.list, fread, .parallel=TRUE, .paropts=list(.options.snow=list(progress=pbu))))

Matching any whole word on the commandline.

I'll be using the phpsh interactive shell on Ubuntu 12.10 to demonstrate the PCRE regex engine through the method known as preg_match

Start phpsh, put some content into a variable, match on word.

el@apollo:~/foo$ phpsh

php> $content1 = 'badger'
php> $content2 = '1234'
php> $content3 = '$%^&'

php> echo preg_match('(\w+)', $content1);
1

php> echo preg_match('(\w+)', $content2);
1

php> echo preg_match('(\w+)', $content3);
0

The preg_match method used the PCRE engine within the PHP language to analyze variables: $content1, $content2 and $content3 with the (\w)+ pattern.

$content1 and $content2 contain at least one word, $content3 does not.

Match a specific words on the commandline without word bountaries

el@apollo:~/foo$ phpsh

php> $gun1 = 'dart gun';
php> $gun2 = 'fart gun';

Variables gun1 and gun2 contain the string dart or fart which is correct, but gun3 contains darty and still matches, that is the problem. So onto the next example.

Match specific words on the commandline with word boundaries:

Word Boundaries can be force matched with \b, see:

Regex Visual Image acquired from http://jex.im/regulex and https://github.com/JexCheng/regulex Example:

el@apollo:~/foo$ phpsh

php> $gun1 = 'dart gun';
php> $gun2 = 'fart gun';
php> $gun3 = 'darty gun';
php> $gun4 = 'unicorn gun';

php> echo preg_match('(\bdart\b|\bfart\b)', $gun1);
1

php> echo preg_match('(\bdart\b|\bfart\b)', $gun2);
1

php> echo preg_match('(\bdart\b|\bfart\b)', $gun3);
0

php> echo preg_match('(\bdart\b|\bfart\b)', $gun4);
0

The \b asserts that we have a word boundary, making sure " dart " is matched, but " darty " isn't.

It is used to escape special characters and print them as is. E.g. to print a double quote which is used to enclose strings, you need to escape it using the backslash character.

e.g.

System.out.println("printing \"this\" in quotes");

outputs

printing "this" in quotes

I have generated 100 different colors of different contrast, and you can increase values according to your need:

Math.seededRandom = function(max, min) {
    max = max || 1;
    min = min || 0;

    Math.seed = (Math.seed * 9301 + 49297) % 233280;
    var rnd = Math.seed / 233280.0;

for(var i=0; i<100; i++)

for(c=0; c<seededRandom.length; c++) {
    //var inc=15;
    for(var i=0; i<seededRandom.length; i++)
    {
        if(i!==c) {
            if(seededRandom[c] == seededRandom[i]) {

    }
    inc = inc > 255 ? 0 : inc;
}

var a=[], b=[], d=[], inc=0, dec=255;
for(c=0; c<seededRandom.length; c++) {
    a[c] = (seededRandom[c] % 100) + inc;
    b[c] = dec - Math.floor(seededRandom[c]/100);
    if(b[c] < 0)
        b[c] = b[c]* - 1;
    if(a[c] > 255)
        a[c] -= 255;
    d[c] = Math.floor(b[c]/2);
    inc += 5;
    dec -= 5;
}


var app = angular.module("myAppp", []).controller('myCtrl',function($scope, $http) {
$scope.id = [];
for(var i=0; i<seededRandom.length; i++)
    $scope.id.push(i);

// Generate random number
$scope.Icon = [];$scope.Icon2 = [], $scope.Icon3 = [];

var ran = 0, inc = 5, dec = 255;
for(var i=0;i<seededRandom.length;i++)
{
    $scope.Icon.push(a[i]%100);
    $scope.Icon2.push(b[i]%100);
    $scope.Icon3.push(d[i]%100);
    console.log(a[i] + "|" + b[i] + "|" + d[i]);
}

});

It works for me and I think it would be helpful for you also.

One best thing in this example is, it will generate 100 random colors and colors would be same on every page load.

It's called case and it works like you would expect, plus lots more fun stuff courtesy of === which implements the tests.

case 5
  when 5
    puts 'yes'
  else
    puts 'else'
end

Now for some fun:

case 5 # every selector below would fire (if first)
  when 3..7    # OK, this is nice
  when 3,4,5,6 # also nice
  when Fixnum  # or
  when Integer # or
  when Numeric # or
  when Comparable # (?!) or
  when Object  # (duhh) or
  when Kernel  # (?!) or
  when BasicObject # (enough already)
    ...
end

And it turns out you can also replace an arbitrary if/else chain (that is, even if the tests don't involve a common variable) with case by leaving out the initial case parameter and just writing expressions where the first match is what you want.

case
  when x.nil?
    ...
  when (x.match /'^fn'/)
    ...
  when (x.include? 'substring')
    ...
  when x.gsub('o', 'z') == 'fnzrq'
    ...
  when Time.now.tuesday?
    ...
end

You can try the following tutorial, it may help you to move forward:

Swift 2.3: UIColor Extension. I Think its simpler.

extension UIColor {
    static func colorFromHex(hexString: String, alpha: CGFloat = 1) -> UIColor {
        //checking if hex has 7 characters or not including '#'
        if hexString.characters.count < 7 {
            return UIColor.whiteColor()
        }
        //string by removing hash
        let hexStringWithoutHash = hexString.substringFromIndex(hexString.startIndex.advancedBy(1))

        //I am extracting three parts of hex color Red (first 2 characters), Green (middle 2 characters), Blue (last two characters)
        let eachColor = [
            hexStringWithoutHash.substringWithRange(hexStringWithoutHash.startIndex...hexStringWithoutHash.startIndex.advancedBy(1)),
            hexStringWithoutHash.substringWithRange(hexStringWithoutHash.startIndex.advancedBy(2)...hexStringWithoutHash.startIndex.advancedBy(3)),
            hexStringWithoutHash.substringWithRange(hexStringWithoutHash.startIndex.advancedBy(4)...hexStringWithoutHash.startIndex.advancedBy(5))]

        let hexForEach = eachColor.map {CGFloat(Int($0, radix: 16) ?? 0)} //radix is base of numeric system you want to convert to, Hexadecimal has base 16

        //return the color by making color
        return UIColor(red: hexForEach[0] / 255, green: hexForEach[1] / 255, blue: hexForEach[2] / 255, alpha: alpha)
    }
}

Usage:

let color = UIColor.colorFromHex("#25ac09")

x->y can mean 2 things. If x is a pointer, then it means member y of object pointed to by x. If x is an object with operator->() overloaded, then it means x.operator->().

In lodash you can use _.includes (which also aliases to _.contains)

You can search the whole array:

_.includes([1, 2, 3], 1); // true

You can search the array from a starting index:

_.includes([1, 2, 3], 1, 1);  // false (begins search at index 1)

Search a string:

_.includes('pebbles', 'eb');  // true (string contains eb)

Also works for checking simple arrays of objects:

_.includes({ 'user': 'fred', 'age': 40 }, 'fred');    // true
_.includes({ 'user': 'fred', 'age': false }, false);  // true

One thing to note about the last case is it works for primitives like strings, numbers and booleans but cannot search through arrays or objects

_.includes({ 'user': 'fred', 'age': {} }, {});   // false
_.includes({ 'user': [1,2,3], 'age': {} }, 3);   // false

In my case, i made separate method for local files, in this file: src/Illuminate/Filesystem/FilesystemAdapter.php

    /**
 * Get the local path for the given filename.
 * @param $path
 * @return string
 */
public function localPath($path)
{
    $adapter = $this->driver->getAdapter();
    if ($adapter instanceof LocalAdapter) {
        return $adapter->getPathPrefix().$path;
    } else {
        throw new RuntimeException('This driver does not support retrieving local path');
    }
}

If it's in input field you're trying to "un-yellow" ...

1. Set a background-color with css... let's say #ccc (light gray).
2. Add value="sometext", which temporary fills the field with "sometext"
3. (optional) Add a little javascript to make the "sometext" clear when you go to put the real text in.

So, it might look like this:

<input id="login" style="background-color: #ccc;" value="username"
    onblur="if(this.value=='') this.value='username';" 
    onfocus="if(this.value=='username') this.value='';" />

When TOP is used with INSERT, UPDATE, MERGE, or DELETE, the referenced rows are not arranged in any order and the ORDER BY clause can not be directly specified in these statements. If you need to use TOP to insert, delete, or modify rows in a meaningful chronological order, you must use TOP together with an ORDER BY clause that is specified in a subselect statement.

TOP cannot be used in an UPDATE and DELETE statements on partitioned views.

TOP cannot be combined with OFFSET and FETCH in the same query expression (in the same query scope). For more information, see http://technet.microsoft.com/en-us/library/ms189463.aspx

You can use substr:

echo substr('a,b,c,d,e,', 0, -1);
# => 'a,b,c,d,e'

#$computerList = "Server Name"
#$regVar = "Name of the package "
#$packageName = "Packe name "

$regVar = $args[1]
$packageName = $args[2]
foreach ($computer in $computerList)

    param(
        $computer,
        $regVar,
        $packageName
        )

        Write-Host "Connected to $computer"
        if ([IntPtr]::Size -eq 4)
        {
            $registryLocation = Get-ChildItem "HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\"
            Write-Host "Connected to 32bit Architecture"
        }

node.js

Node.js is a javascript motor for the server side.
In addition to all the js capabilities, it includes networking capabilities (like HTTP), and access to the file system.
This is different from client-side js where the networking tasks are monopolized by the browser, and access to the file system is forbidden for security reasons.

node.js as a web server: express

Something that runs in the server, understands HTTP and can access files sounds like a web server. But it isn't one.
To make node.js behave like a web server one has to program it: handle the incoming HTTP requests and provide the appropriate responses.
This is what Express does: it's the implementation of a web server in js.
Thus, implementing a web site is like configuring Express routes, and programming the site's specific features.

Middleware and Connect

Serving pages involves a number of tasks. Many of those tasks are well known and very common, so node's Connect module (one of the many modules available to run under node) implements those tasks.
See the current impressing offering:

• logger request logger with custom format support
• csrf Cross-site request forgery protection
• compress Gzip compression middleware
• basicAuth basic http authentication
• bodyParser extensible request body parser
• json application/json parser
• urlencoded application/x-www-form-urlencoded parser
• multipart multipart/form-data parser
• timeout request timeouts
• cookieParser cookie parser
• session session management support with bundled MemoryStore
• cookieSession cookie-based session support
• methodOverride faux HTTP method support
• responseTime calculates response-time and exposes via X-Response-Time
• staticCache memory cache layer for the static() middleware
• static streaming static file server supporting Range and more
• directory directory listing middleware
• vhost virtual host sub-domain mapping middleware
• favicon efficient favicon server (with default icon)
• limit limit the bytesize of request bodies
• query automatic querystring parser, populating req.query
• errorHandler flexible error handler

Connect is the framework and through it you can pick the (sub)modules you need.
The Contrib Middleware page enumerates a long list of additional middlewares.
Express itself comes with the most common Connect middlewares.

What to do?

Install node.js.
Node comes with npm, the node package manager.
The command npm install -g express will download and install express globally (check the express guide).
Running express foo in a command line (not in node) will create a ready-to-run application named foo. Change to its (newly created) directory and run it with node with the command node <appname>, then open http://localhost:3000 and see. Now you are in.

Using control-z suspends the process (see the output from stty -a which lists the key stroke under susp). That leaves it running, but in suspended animation (so it is not using any CPU resources). It can be resumed later.

If you want to stop a program permanently, then any of interrupt (often control-c) or quit (often control-\) will stop the process, the latter producing a core dump (unless you've disabled them). You might also use a HUP or TERM signal (or, if really necessary, the KILL signal, but try the other signals first) sent to the process from another terminal; or you could use control-z to suspend the process and then send the death threat from the current terminal, and then bring the (about to die) process back into the foreground (fg).

Note that all key combinations are subject to change via the stty command or equivalents; the defaults may vary from system to system.

You need to create a directory on a remote server. Then use "git init" command to set it as a repository. This should be done for each new project you have (each new folder)

Assuming you have already setup and used git using ssh keys, I wrote a small Python script, which when executed from a working directory will set up a remote and initialize the directory as a git repo. Of course, you will have to edit script (only once) to tell it server and Root path for all repositories.

Version 1.18 of Lombok introduced the @SuperBuilder annotation. We can use this to solve our problem in a simpler way.

You can refer to https://www.baeldung.com/lombok-builder-inheritance#lombok-builder-and-inheritance-3.

so in your child class, you will need these annotations:

@Data
@SuperBuilder
@NoArgsConstructor
@EqualsAndHashCode(callSuper = true)

in your parent class:

@Data
@SuperBuilder
@NoArgsConstructor

You first need to uninstall the ruby installed by Ubuntu with something like sudo apt-get remove ruby.

Then reinstall ruby using rbenv and ruby-build according to their docs:

cd $HOME
sudo apt-get update 
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev

git clone https://github.com/rbenv/rbenv.git ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL

git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL

rbenv install 2.3.1
rbenv global 2.3.1
ruby -v

The last step is to install Bundler:

gem install bundler
rbenv rehash

Then enjoy!

Have you considered List.BinarySearch(item)?

You said that your large collection is already sorted so this seems like the perfect opportunity? A hash would definitely be the fastest, but this brings about its own problems and requires a lot more overhead for storage.

Team Foundation Server 2015 (on-premises) and Visual Studio Team Services (cloud version) include built-in support for searching across all your code and work items.

You can do simple string searches like foo, boolean operations like foo OR bar or more complex language-specific things like class:WebRequest

You can read more about it here: https://www.visualstudio.com/en-us/docs/search/overview

(Update: August 2011)

As geofflane mentions in his answer, Java 7 now support named groups.
tchrist points out in the comment that the support is limited.
He details the limitations in his great answer "Java Regex Helper"

Java 7 regex named group support was presented back in September 2010 in Oracle's blog.

In the official release of Java 7, the constructs to support the named capturing group are:

• (?<name>capturing text) to define a named group "name"
• \k<name> to backreference a named group "name"
• ${name} to reference to captured group in Matcher's replacement string
• Matcher.group(String name) to return the captured input subsequence by the given "named group".

Other alternatives for pre-Java 7 were:

• Google named-regex (see John Hardy's answer)
  Gábor Lipták mentions (November 2012) that this project might not be active (with several outstanding bugs), and its GitHub fork could be considered instead.
• jregex (See Brian Clozel's answer)

(Original answer: Jan 2009, with the next two links now broken)

You can not refer to named group, unless you code your own version of Regex...

That is precisely what Gorbush2 did in this thread.

Regex2

(limited implementation, as pointed out again by tchrist, as it looks only for ASCII identifiers. tchrist details the limitation as:

only being able to have one named group per same name (which you don’t always have control over!) and not being able to use them for in-regex recursion.

Note: You can find true regex recursion examples in Perl and PCRE regexes, as mentioned in Regexp Power, PCRE specs and Matching Strings with Balanced Parentheses slide)

Example:

String:

"TEST 123"

RegExp:

"(?<login>\\w+) (?<id>\\d+)"

Access

matcher.group(1) ==> TEST
matcher.group("login") ==> TEST
matcher.name(1) ==> login

Replace

matcher.replaceAll("aaaaa_$1_sssss_$2____") ==> aaaaa_TEST_sssss_123____
matcher.replaceAll("aaaaa_${login}_sssss_${id}____") ==> aaaaa_TEST_sssss_123____

A new library called ts-optchain provides this functionality, and unlike lodash' solution, it also keeps your types safe, here is a sample of how it is used (taken from the readme):

import { oc } from 'ts-optchain';

interface I {
  a?: string;
  b?: {
    d?: string;
  };
  c?: Array<{
    u?: {
      v?: number;
    };
  }>;
  e?: {
    f?: string;
    g?: () => string;
  };
}

const x: I = {
  a: 'hello',
  b: {
    d: 'world',
  },
  c: [{ u: { v: -100 } }, { u: { v: 200 } }, {}, { u: { v: -300 } }],
};

// Here are a few examples of deep object traversal using (a) optional chaining vs
// (b) logic expressions. Each of the following pairs are equivalent in
// result. Note how the benefits of optional chaining accrue with
// the depth and complexity of the traversal.

oc(x).a(); // 'hello'
x.a;

oc(x).b.d(); // 'world'
x.b && x.b.d;

oc(x).c[0].u.v(); // -100
x.c && x.c[0] && x.c[0].u && x.c[0].u.v;

oc(x).c[100].u.v(); // undefined
x.c && x.c[100] && x.c[100].u && x.c[100].u.v;

oc(x).c[100].u.v(1234); // 1234
(x.c && x.c[100] && x.c[100].u && x.c[100].u.v) || 1234;

oc(x).e.f(); // undefined
x.e && x.e.f;

oc(x).e.f('optional default value'); // 'optional default value'

Welcome BrowserDetect - an awesome function.

<script>
    var BrowserDetect;
    BrowserDetect = {...};//  get BrowserDetect Object from the link referenced in this answer
    BrowserDetect.init();
    // On page load, detect browser (with jQuery or vanilla)
    if (BrowserDetect.browser === 'Explorer') {
      // Add 'ie' class on every element on the page.
      $('*').addClass('ie');
    }
</script>

<!-- ENSURE IE STYLES ARE AVAILABLE -->
<style>
    div.ie {
       // do something special for div on IE browser.
    }
    h1.ie {
     // do something special for h1 on IE browser.
    }
</style>

The Object BrowserDetect also provides version info so we can add specific classes - for ex. $('*').addClass('ie9'); if (BrowserDetect.version == 9).

Good Luck....

There is no single function that does what you want. Your definition of shift is slightly different than what most people are doing. The ways to shift an array are more commonly looped:

>>>xs=np.array([1,2,3,4,5])
>>>shift(xs,3)
array([3,4,5,1,2])

However, you can do what you want with two functions.
Consider a=np.array([ 0., 1., 2., 3., 4., 5., 6., 7., 8., 9.]):

def shift2(arr,num):
    arr=np.roll(arr,num)
    if num<0:
         np.put(arr,range(len(arr)+num,len(arr)),np.nan)
    elif num > 0:
         np.put(arr,range(num),np.nan)
    return arr
>>>shift2(a,3)
[ nan  nan  nan   0.   1.   2.   3.   4.   5.   6.]
>>>shift2(a,-3)
[  3.   4.   5.   6.   7.   8.   9.  nan  nan  nan]

After running cProfile on your given function and the above code you provided, I found that the code you provided makes 42 function calls while shift2 made 14 calls when arr is positive and 16 when it is negative. I will be experimenting with timing to see how each performs with real data.

Just Found 3 simple steps to alter already existing column that was null before

update   orders
set BasicHours=0 where BasicHours is null

alter table orders 
add default(0) for BasicHours

alter table orders 
alter  column CleanBasicHours decimal(7,2) not null 

If you want to take advantage of the 60FPS smoothness that the "transform" property offers, you can combine the two:

@keyframes changewidth {
  from {
    transform: scaleX(1);
  }

  to {
    transform: scaleX(2);
  }
}

div {
  animation-duration: 0.1s;
  animation-name: changewidth;
  animation-iteration-count: infinite;
  animation-direction: alternate;
}

More explanation on why transform offers smoother transitions here: https://medium.com/outsystems-experts/how-to-achieve-60-fps-animations-with-css3-db7b98610108

Method 1:

public void onClick(View v) {
          Intent i = new Intent(currentActivity.this, SecondActivity.class);
         startActivty(i);
        }

Method 2:

Button button = (Button) findViewById(R.id.mybutton);
 button.setOnClickListener(new OnClickListener() {

    public void onClick(View v) {
         Toast.makeText(this, "Button Clicked", Toast.LENGTH_LONG).show();

    }
 });

Your json isn't an array, it hasn't length property. You must change your data return or the way you get your data count.

I am using something like this - codeigniter-htaccess-file, its a good article to begin with.

• leave the .htaccess file in CI root dir
• make sure that mod_rewrite is on
• check for typos (ie. controller file/class name)
• in /application/config/config.php set $config['index_page'] = "";
• in /application/config/routes.php set your default controller $route['default_controller']="home";

If you are running clean installation of CI (2.1.3) there isn't really much that could be wrong.

• 2 config files
• controller
• .htaccess
• mod_rewrite

A switch statement can only be used for integral values, not for values of user-defined type. And even if it could, your input operation doesn't work, either.

You might want this:

#include <string>
#include <iostream>


std::string input;

if (!std::getline(std::cin, input)) { /* error, abort! */ }

if (input == "Option 1")
{
    // ... 
}
else if (input == "Option 2")
{ 
   // ...
}

// etc.

  angular.service('myService', myServiceFunction);
  angular.factory('myFactory', myFactoryFunction);

I had trouble wrapping my head around this concept until I put it to myself this way:

Service: the function that you write will be new-ed:

  myInjectedService  <----  new myServiceFunction()

Factory: the function (constructor) that you write will be invoked:

  myInjectedFactory  <---  myFactoryFunction()

What you do with that is up to you, but there are some useful patterns...

Such as writing a service function to expose a public API:

function myServiceFunction() {
  this.awesomeApi = function(optional) {
    // calculate some stuff
    return awesomeListOfValues;
  }
}
---------------------------------------------------------------------------------
// Injected in your controller
$scope.awesome = myInjectedService.awesomeApi();

Or using a factory function to expose a public API:

function myFactoryFunction() {
  var aPrivateVariable = "yay";

  function hello() {
    return "hello mars " + aPrivateVariable;
  }
  
  // expose a public API
  return {
    hello: hello
  };
}
---------------------------------------------------------------------------------
// Injected in your controller
$scope.hello = myInjectedFactory.hello();

Or using a factory function to return a constructor:

function myFactoryFunction() {
    return function() {
        var a = 2;
        this.a2 = function() {
            return a*2;
        };
    };
}
---------------------------------------------------------------------------------
// Injected in your controller
var myShinyNewObject = new myInjectedFactory();
$scope.four = myShinyNewObject.a2();

Which one to use?...

You can accomplish the same thing with both. However, in some cases the factory gives you a little bit more flexibility to create an injectable with a simpler syntax. That's because while myInjectedService must always be an object, myInjectedFactory can be an object, a function reference, or any value at all. For example, if you wrote a service to create a constructor (as in the last example above), it would have to be instantiated like so:

var myShinyNewObject = new myInjectedService.myFunction()

which is arguably less desirable than this:

var myShinyNewObject = new myInjectedFactory();

(But you should be wary about using this type of pattern in the first place because new-ing objects in your controllers creates hard-to-track dependencies that are difficult to mock for testing. Better to have a service manage a collection of objects for you than use new() wily-nilly.)

One more thing, they are all Singletons...

Also keep in mind that in both cases, angular is helping you manage a singleton. Regardless of where or how many times you inject your service or function, you will get the same reference to the same object or function. (With the exception of when a factory simply returns a value like a number or string. In that case, you will always get the same value, but not a reference.)

You check if it's null in C# like this:

if(MyObject != null) {
  //do something
}

If you want to check against default (tough to understand the question on the info given) check:

if(MyObject != default(MyObject)) {
 //do something
}

Hash tables are O(1) average and amortized case complexity, however it suffers from O(n) worst case time complexity. [And I think this is where your confusion is]

Hash tables suffer from O(n) worst time complexity due to two reasons:

1. If too many elements were hashed into the same key: looking inside this key may take O(n) time.
2. Once a hash table has passed its load balance - it has to rehash [create a new bigger table, and re-insert each element to the table].

However, it is said to be O(1) average and amortized case because:

1. It is very rare that many items will be hashed to the same key [if you chose a good hash function and you don't have too big load balance.
2. The rehash operation, which is O(n), can at most happen after n/2 ops, which are all assumed O(1): Thus when you sum the average time per op, you get : (n*O(1) + O(n)) / n) = O(1)

Note because of the rehashing issue - a realtime applications and applications that need low latency - should not use a hash table as their data structure.

EDIT: Annother issue with hash tables: cache
Another issue where you might see a performance loss in large hash tables is due to cache performance. Hash Tables suffer from bad cache performance, and thus for large collection - the access time might take longer, since you need to reload the relevant part of the table from the memory back into the cache.

Here's a list splitting routine I wrote a couple months ago:

public static List<List<T>> Chunk<T>(
    List<T> theList,
    int chunkSize
)
{
    List<List<T>> result = theList
        .Select((x, i) => new {
            data = x,
            indexgroup = i / chunkSize
        })
        .GroupBy(x => x.indexgroup, x => x.data)
        .Select(g => new List<T>(g))
        .ToList();

    return result;
}

Android Studio has recently published an official guide for low-memory machines: Guide

If you are running Android Studio on a machine with less than the recommended specifications (see System Requirements), you can customize the IDE to improve performance on your machine, as follows:

• Reduce the maximum heap size available to Android Studio: Reduce the maximum heap size for Android Studio to 512Mb.

• Update Gradle and the Android plugin for Gradle: Update to the latest versions of Gradle and the Android plugin for Gradle to ensure you are taking advantage of the latest improvements for performance.

• Enable Power Save Mode: Enabling Power Save Mode turns off a number of memory- and battery-intensive background operations, including error highlighting and on-the-fly inspections, autopopup code completion, and automatic incremental background compilation. To turn on Power Save Mode, click File > Power Save Mode.

• Disable unnecessary lint checks: To change which lint checks Android Studio runs on your code, proceed as follows: Click File > Settings (on a Mac, Android Studio > Preferences) to open the Settings dialog.In the left pane, expand the Editor section and click Inspections. Click the checkboxes to select or deselect lint checks as appropriate for your project. Click Apply or OK to save your changes.

• Debug on a physical device: Debugging on an emulator uses more memory than debugging on a physical device, so you can improve overall performance for Android Studio by debugging on a physical device.

• Include only necessary Google Play Services as dependencies: Including Google Play Services as dependencies in your project increases the amount of memory necessary. Only include necessary dependencies to improve memory usage and performance. For more information, see Add Google Play Services to Your Project.

• Reduce the maximum heap size available for DEX file compilation: Set the javaMaxHeapSize for DEX file compilation to 200m. For more information, see Improve build times by configuring DEX resources.

• Do not enable parallel compilation: Android Studio can compile independent modules in parallel, but if you have a low-memory system you should not turn on this feature. To check this setting, proceed as follows: Click File > Settings (on a Mac, Android Studio > Preferences) to open the Settings dialog. In the left pane, expand Build, Execution, Deployment and then click Compiler. Ensure that the Compile independent modules in parallel option is unchecked.If you have made a change, click Apply or OK for your change to take effect.

• Turn on Offline Mode for Gradle: If you have limited bandwitch, turn on Offline Mode to prevent Gradle from attempting to download missing dependencies during your build. When Offline Mode is on, Gradle will issue a build failure if you are missing any dependencies, instead of attempting to download them. To turn on Offline Mode, proceed as follows:

  • Click File > Settings (on a Mac, Android Studio > Preferences) to open the Settings dialog.

  • In the left pane, expand Build, Execution, Deployment and then click Gradle.

  • Under Global Gradle settings, check the Offline work checkbox.

  • Click Apply or OK for your changes to take effect.

Yes, the value returned is the value after and before the incrementation, respectively.

class Foo {
    public static void main(String args[]) {
        int x = 1;
        int a = x++;
        System.out.println("a is now " + a);
        x = 1;
        a = ++x;
        System.out.println("a is now " + a);
    }
}

$ java Foo
a is now 1
a is now 2

function setCookie(name,value,days) {

   if (days) {
       var date = new Date();
       date.setTime(date.getTime() + (days*24*60*60*1000));
       expires = "; expires=" + date.toUTCString();
   }
    document.cookie = name + "=" + (value || "")  + expires + "; path=/";
}

 function getCookie(name) {
   var nameEQ = name + "=";
   var ca = document.cookie.split(';');
   for(var i=0;i < ca.length;i++) {
       var c = ca[i];
       while (c.charAt(0)==' ') c = c.substring(1,c.length);
        if (c.indexOf(nameEQ) == 0) return 
        c.substring(nameEQ.length,c.length);

SSL development libraries have to be installed

CentOS:

$ yum install openssl-devel libffi-devel

Ubuntu:

$ apt-get install libssl-dev libffi-dev

OS X (with Homebrew installed):

$ brew install openssl

There is Task exists, It is unnesscery using BackgroundWorker, Task is more simple. for example:

ProgressDialog.cs:

   public partial class ProgressDialog : Form
    {
        public System.Windows.Forms.ProgressBar Progressbar { get { return this.progressBar1; } }

        public ProgressDialog()
        {
            InitializeComponent();
        }

        public void RunAsync(Action action)
        {
            Task.Run(action);
        }
    }

Done! Then you can reuse ProgressDialog anywhere:

var progressDialog = new ProgressDialog();
progressDialog.Progressbar.Value = 0;
progressDialog.Progressbar.Maximum = 100;

progressDialog.RunAsync(() =>
{
    for (int i = 0; i < 100; i++)
    {
        Thread.Sleep(1000)
        this.progressDialog.Progressbar.BeginInvoke((MethodInvoker)(() => {
            this.progressDialog.Progressbar.Value += 1;
        }));
    }
});

progressDialog.ShowDialog();

Pandas >= 0.21

set_value has been deprecated. You can now use DataFrame.at to set by label, and DataFrame.iat to set by integer position.

Setting Cell Values with at/iat

# Setup
df = pd.DataFrame({'A': [12, 23], 'B': [['a', 'b'], ['c', 'd']]})
df

    A       B
0  12  [a, b]
1  23  [c, d]

df.dtypes

A     int64
B    object
dtype: object

If you want to set a value in second row of the "B" to some new list, use DataFrane.at:

df.at[1, 'B'] = ['m', 'n']
df

    A       B
0  12  [a, b]
1  23  [m, n]

You can also set by integer position using DataFrame.iat

df.iat[1, df.columns.get_loc('B')] = ['m', 'n']
df

    A       B
0  12  [a, b]
1  23  [m, n]

What if I get ValueError: setting an array element with a sequence?

I'll try to reproduce this with:

df

    A   B
0  12 NaN
1  23 NaN

df.dtypes

A      int64
B    float64
dtype: object

df.at[1, 'B'] = ['m', 'n']
# ValueError: setting an array element with a sequence.

This is because of a your object is of float64 dtype, whereas lists are objects, so there's a mismatch there. What you would have to do in this situation is to convert the column to object first.

df['B'] = df['B'].astype(object)
df.dtypes

A     int64
B    object
dtype: object

Then, it works:

df.at[1, 'B'] = ['m', 'n']
df

    A       B
0  12     NaN
1  23  [m, n]

Possible, But Hacky

Even more wacky, I've found you can hack through DataFrame.loc to achieve something similar if you pass nested lists.

df.loc[1, 'B'] = [['m'], ['n'], ['o'], ['p']]
df

    A             B
0  12        [a, b]
1  23  [m, n, o, p]
